WIND-SHIELD.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed June 6, 1908. Serial No. 437,176.

T 0 all whom it may concern:

Be it known that I, MILTON TIBBETTS, a citizen of the United States, and resident of Detroit, in the county of \Vayne and State of Michigan, have invented certain new and useful Improvements in lVind-Shields, of which the following is a specification.

This invention relates to wind shields for motor vehicles, and has particular reference to such shields made up of an upper and lower sash, which are adapted to fold together.

Its objects are to provide means for easily and conveniently bringing the upper sash into a position against the lower sash w thout utilizing much room in the operation. so that there will be no interference by the numerous parts of the vehicle which would be in the way if the sashes were hinged together to fold in the ordinary way.

To this end my invention embodies mechanism by which the upper sash may be lowered in a vertical plane parallel with the lower sash, and close against said lower sash. Briefly stated, the sashes fold by a relative endwise motion of pure translation in a circular path.

Other features and details of my invention will be apparent from the following description and claims.

In the accompanying drawings :F1gure 1 is a front view of a portion of a motor vehicle lmving one form of my wind shield applied thereto; Fig. 2 is a side view of what is shown in Fig. 1; Fig. 3 is an enlarged edge view of a portion of the two sashes viewed from opposite sides, the sashes being in normal position and in line; Fig. 4 is a similar view showing the upper sash pulled out to a. position out of line with the lower sash and ready to be lowered: Fig. 5 is a similar view showing the upper sash in lowered position; Fig. 6 is a detail sectional view of the pivot joint for the arm carrying the upper sash; Fig. 7 is a cross section on the line 77 of Fig. 6, showing my split sleeve arrangement for clamping the pivot joint; Fig. 8 is a sectional view showing the meeting edges of the two sashes when in position, one above the other; Fig. 9 is a rear view of the two sashes with the upper sash partly lowered; Fig. 10 is a rear view of the two sashes in normal position, and showing a modified form of means for lowering the upper sash; Fig. 11 is an edge view of what is shown in Fig. 10; Fig. 12 is a detail view of the modified pivot arms and cams for automatically moving the upper sash out of line with the lower sash; and Fig. 13 is a similar view showing the position of the pivot arms and cams when the upper sash is in lowered position.

In these drawings, 1 represents the side bar of the vehicle frame, 2 represents the engine housing, and 3 represents the dashboard of the vehicle.

My wind shield is mounted on the dashboard 3 and is composed of a lower stationary sash l, and the upper movable sash 5, which sashes in normal use are in line one above the other. The lower sash is supported by the brace rods 6 connected with the frame.

In the form shown in Figs. 1 to 9, the up per sash is connected to the lower sash by the pivot arms 7 which have direct pivotal connection with ears 8 secured to the upper sash. The other ends of said arms carry short pivot shafts 9 which have at their outer ends enlarged heads 10. and these shafts 9 fit within split sleeves 11, carried by the bracket 12 mounted upon the upper edge of the lower sash. The sleeve 11 has at its inner end an interior flange 13, against which the enlarged head 10 of the shaft 9 abuts. The flange 13 has therein a slot 11 within which fits the rib 15 which is carried by the shaft 9, and which extends throughout a portion of the length of said shaft. It will be observed that this arrangement of the lower pivot joint of the arm permits those arms to be moved laterally a certain distance which will be made suflicient to bring the two sashes out of line, as shown, and it will further be observed that the cooperating action of the rib 15 and slot 14 prevents the arms turning on the pivot until the sashes have been moved out of line. In this form the upper sash is to be pulled out of line with the lower sash by manual operation of the handles 16, and since a pull on these handles would tend to twist the upper sash on the upper pivotal connection I have provided means for connecting the bottom part of the upper sash with the casing of the lower pivot during this lateral movement of the sash. This means embodies a hook 17 on the bottom of the upper sash, and an eye 18 on the bottom of the arm, and it will be observed that the turning of the link i arms 7 upon their pivots will at once disconnect this hook and eye. The other link arm 7 is provided with an eye 24* adapted to be engaged by a pin on the upper sash.

The split sleeve 11 is provided with a free end 19 which tends to separate from the other part of the sleeve by its resiliency, and which may be brought toward that other part by the thumb screw 20, thus clamping the sleeve on the shaft 9 and its enlarged end 10. The split sleeve clamp thus enables me to firmly and securely fasten the upper sash in position over the lower sash, or to hold it in any desired position.

In the form shown in Fig. 1 the lower sash is provided with upwardly inclined portions or lugs 21 at its ends, and the upper sash has cutaway portions 22, fitting against these lugs, thus holding the upper sash more securely in place.

By reason of the position of other parts of the motor vehicle it is necessary to lower the upper sash behind the lower sash, and where the upper sash is to be moved laterally in a straight line until it is out of line with the lower sash the meeting edges of the sashes cannot be made inclined forward and downward, but are preferably made with an incline rearward and downward. This inclination however, while facilitating the rearward movement of the upper sash, will permit the passage of water, striking the front of the shield, down between the sashes, and to avoid this 1 have made the meeting edges of the sashes in the form shown in Fig. 8. In this form the top of the lower sash is made in the shape of an inverted V, and the upper sash is made with a surface inclined rearward and downward, but has on its front side a depending lip 23. \Vater striking the upper sash will pass downward and drop from the point of this lip, passing down the front side of the lower sash and will not pass back through the joint to the rear side of the sash, and the V-shape of the lower sash will allow this lip to pass over that sash without contact therewith, and at the same time will permit the meeting edges of the two sashes to be at an incline rearward and downward.

It will be observed that the arm 7 at one end of the sash is placed in line with the sash as shown at the left in Figs. 3 and 4, and that at the other end of the sash the arm 7 is placed immediately at one side of the sash. This is of course necessary, since in swinging upon the pivot arms the sash has some endwise motion and consequently both pivot arms could not be in line with it. As shown in Fig. 5 when the upper sash is in lowered position, the hook 17 engages in an opening in the lower sash, thus holding sashes in proper position, and upon the other end of the sash there is a pin 24 which engages an opening in plate 25 on the lower sash.

The parallel link arms 7 connected at opposite ends of the sashes will permit the upper sash to be moved endwise in the arc of a circle, and to be lowered vertically in a plane parallel with the lower sash, but it will be apparent that during this lowering operation performed by hand there will be one point reached where one end of the upper sash may be made to move upward, while the other moves downward, and that thus the connections may be broken or the sash left standing at an angle. To avoid this accidental disarrangement of the mechanism the two pivot arms may be connected so that they will necessarily move together, and that there will be no dead center or point at which they may be turned in opposite directions. Any suitable means may be used connecting the two arms for this purpose, and in Fig. 9 I have shown a rod 26 pivotally connected to ears 27 on the arms 7 so as to prevent this accidental twisting of the sash.

In the modified form shown in Figs. 10 to 13 I have disclosed an automatic means for moving the two sashes out of line at the commencement of the swinging operation used in lowering the upper sash. It will be understood that most of the features described in connection with the other form of the invention shown are also applicable to this modification, and that this modification is applicable to the form shown in the other figures. In this modified form a link arm 28 is pivotally connected to the lower sash at its top at 29, and this arm extends at an inclination and is pivotally connected to a bracket 30 extending outwardly from the upper sash. At the other end of the sashes the link arm 31 is pivotally connected to the upper sash at 32 and is pivotally connected at its lower end to a bracket 33 extending outwardly from the top of the lower sash, thus making the arm 31 stand at an inclination parallel to the arm 28. This inclined arrangement of the link arms is used 0 so that the upper sash, when moved to the right in Fig. 10, will be automatically elevated above the lower sash during the first part of the swinging operation, and so that the meeting edges of the two sashes may be made upon a plane extending forward and downward, as clearly shown in Fig. 12, without interfering with the rearward movement of the upper sash. In this form the rearward movement of the upper sash is secured by the action of cam surfaces on the pivot sleeve 3i, and upon the lower end of the link arm, as shown at 35. In this instance the link arm has sliding pivotal connection with the sleeve in substantially the same way as shown in Figs. 3 to 6, except that there are no key connections between the parts. The cam surfaces may be of any desired form which will have the effect of moving the arms laterally as desired, and consequently lengthwise of the pivot joint, and in Figs. 12 and 13 I have shown one form of cam for doing this. In this particular form the sleeve 34 has an inclined surface 36, against which bears a similar surface on the link arm, and it will be understood that there is another inclined surface like 36 and having the same inclination, thus forming practically a cam groove into which a portion of the link arm passes. The result is that when the link arms are turned in one direction the upper sash is automatically moved out of line with the lower sash, and when turned in the opposite direction the two sashes are automatically moved into a line. In the particular form shown, it is necessary by slight pressure on the part to bring the two cam surfaces into operation, but it is of course obvious that this might be done automatically. In this form of the invention I have provided bolts 37 on the ends of the upper sash adapted to lock the sash in position, thus preventing accidental turning of the sash upon the link arms.

It will be understood that when the upper sash is moved rearwardly an opening is formed between the sashes permitting the passage of a current of air. The upper sash may be held in this position by the clamping action of the split sleeves 11.
